Usage:widely used for engineering machinery, auto parts, fasteners, bearings, chains, metal tools and precision parts industries quenching carburizing. Features: (1)electricity-saving:adopt high tensile calcium silicate board, ceramic fiber board, heat-resistant material for high Performance. (2)operation:adopt automatic control to save manual cost. (3)quality:equipped with a variable step string fan on the top of the furnace to get uniform temperature for high quality.  (4) atmosphere:adopt methanol decomposition to stabilize gas and to ensure for quality.  (5) stability: cp value tolerance±0.03%(carbon potential), and temperature equally dispersed at ±5?.
